Eighties boyband Bros have been forced to cancel over half the dates on their comeback tour due to "unforeseen circumstances".

After 24 years away from the pop game, Matt and Luke Goss announced their comeback in late 2016 and were due to gig around the country later this year. And the pair's return went down a storm, with their London shows reportedly selling out in seven seconds.

But now the boys have had to reduce the seven-date tour to just three; two in London and one in Manchester. Dates in Glasgow, Newcastle, Nottingham and Birmingham will not go ahead.

Dates were cancelled due to "unforeseen logistical circumstances", according to a statement.

The tour was announced to great fanfare, and the dates would be their first shows together since headlining Wembley Stadium in 1989 in front of a 77,000-strong crowd.

When tickets went on sale, the brothers were overwhelmed by the public's response to their comeback.

"We're so excited to play these shows, we wish it was next week," they said. "Summer can't come soon enough."

Ticket holders for the cancelled shows will be refunded, according to the statement from the band.

Bros had announced they were reuniting for the first time since 1992 last October.

The band had eight top 10 hits and three top 20 albums between 1988 and 1991.

Since the split lead singer Matt has been working a residency in Las Vegas and Luke has appeared in a string of Hollywood films including Blade II. Former bass player Craig Logan left the band in 1989 to focus on songwriting.
